I have adaptive cruise control and use it for 99% of the miles I drive.
Speed limit sign recognition which turns red should I stray over the limit, not 100% accurate, but much better that a previous car's iteration, which seemed to make them up as it went along!
Lane Assist which is poor and I have it turned off for 99% of the miles I drive, as it is not very good at recognising anything other than a lane clearly marked on both sides by some form of white lines.
Automatic lights including, if I want to select it, automatic dip. I have to manually switch them on in fog, but they work well with regard to light levels.
Proximity sensors, which help manoeuvres in tight spots, given the bonnet falls away from sight long before it ends.
Reversing camera which is a boon as the rear window sill is so high bollards lurk out of sight!
Airbags galore.
Emergency braking which comes on hard and fast if needed, I tested it with an empty cardbox acting as an obstacle and from 30mph the car damn nearly put me through the windscreen, but it didn't touch the box!
I feel the car is safer than my earlier cars, helps me drive better and safer. While maintaining the correct speeds to comply with limits I can be looking out for hazards 100% of the time.
